London: Teenage girls in US are indulging in more sexual contact with each other than ever before, a study has found. Sexual activity between young girls is reported to have gone up in the last decade, while teenage pregnancy has gone down.

New analysis of the US National Survey of Family Growth (NSFG) has revealed the surprising shifts in the sexual activity.

After comparing NSFG data of 2002 and figures collected between 2006 and 2008, the was found that 11 percent of 17-year-old girls in the more recent statistics had engaged in contact with other girls, compared to just five percent in 2002.

The same girls also claim to have had significantly less heterosexual sexual contact, at just 46 percent in 2006-2008, compared with 63 percent in 2002.
